described by Bartlaub, although do mention is made of the inclusion of elongata in the 

 synonymy oi flagellata. The east African specimens are herein regarded as represent- 

 ing D. afra (see page 558). 



I examined the type specimens of Alecto flagellata and A. elongata at the Leyden 

 Museum in 1910, and in a paper on the crinoids of that museum published in 1911 I 

 placed Alecto elongata in the synonymy of Dichrometra flagellata and gave extended 

 notes on both specimens. 



In a paper on the crinoids of the Berlin Museum published in 1912, I recorded a 

 specimen of Dichrometra flagellata from Singapore collected by Prof. J. Midler. 

 Professor Midler never visited Singapore; the specimen in reality was one of those 

 collected by Jagor and described by Hartlaub in 1891. 



In a paper on the crinoids of the Hamburg Museum published in 1912, 1 described 

 the specimen from the Pelew Islands previously recorded by Hartlaub, and another 

 that had been collected by Dr. G. Duncker at Pitiiu in the Admiralty Islands. 



In my memoir on the crinoids of the Indian Ocean published in 1912, I placed 

 Alecto elongata in the synonymy of Dichrometra flagellata and gave extended notes on 

 the type specimens of both flagellata and elongata. I also compared flagellata with 

 the new species Dichrometra ciliata. In my description of Dichrometra tenuicirra 

 published in 1912, I compared this new form with D. flagellata. 



Hartlaub in 1912 described in detail and figured a specimen of Antedon elongata 

 from the North China Sea that had been collected by the United States North Pacific 

 Exploring Expedition. This specimen had been sent to Carpenter with the Blake 

 collection, and after Carpenter's death it had been sent to Hartlaub with that collection. 



In a paper on the crinoids of the British Museum published in 1913, I recorded 

 five specimens of Dichrometra flagellata from Pulau Obin, Singapore Island, and in a 

 paper on a collection of crinoids made by Captain Suensson in eastern Asia published 

 in the same year I recorded and gave notes on a specimen from Hongkong. 



Dr. Robert Hartmeyer in a paper published in 1916 corrected my record of a 

 specimen in the Berlin Museum from Singapore, and recorded another from the 

 same locality that had been collected by Prof. Edouard von Martens. 



In my memoir on the comatulids collected by the Siboga expedition I recorded 

 and gave notes on specimens of Dichrometra flagellata collected at stations 43, 144, 

 213, and 250.
